2024年5月28日 · The compound HIO4 is called periodic (purr -eye- od -ik)acid, or iodic (VII) acid. Periodic refers to per-iodic, and not periodic as in the Periodic Table.

2024年5月22日 · HIO4 is an iodine oxoacid widely referred to as periodic acid (in Dutch: Periodsaeure, and Ueberiodsaeure) and hyperiodic acid (as HIO4). It is also referred to as …

2020年8月21日 · In all oxidation reactions of glucose, it seems that the aldehyde group alone gets oxidised and none of the hydroxyl groups. In one reaction with nitric acid, the aldehyde group …

2019年12月20日 · $\\ce{HIO4_{(aq)}}$ requires the vicinal diols to have syn configuration, as it forms a cyclic periodate ester. But glucose does not have syn configuration at C3, and if you …

2024年6月1日 · In HIO4 (periodic acid), the oxidation number of hydrogen (H) is +1, of iodine (I) is +7, and of oxygen (O) is -2. Therefore, the overall oxidation number of HIO4 is zero since the …

2015年4月30日 · Carbohydrate like glucose undergoes periodic cleavage by $\\ce{HIO4}$ and forms respective products are five moles of formic acid and one mole of formaldehyde. Here is …

2016年8月14日 · So I was looking at factors that control the relative strengths of acids and bases. We know that HI H I is a stronger acid that HBr H B r because I I is a much larger atom. But …

2024年6月1日 · HIO4 (periodic acid) is commonly used in organic synthesis to cleave vicinal diols to aldehydes and ketones, a process known as periodate cleavage.

Periodic acid (per-iodic acid, $\\ce{HIO4}$ ) cleaves vicinal diols(to carbonyls) via a cyclic intermediate. Due to the cyclic intermediate, it needs a syn configuration for the $\\ce{-OH}$ …

2021年4月28日 · The following reaction seem to be valid; $\\ce{CH2OH-CHOH-CH2OH ->[HIO4]CH2O + HCOOH + CH2O + 2H2O}$ Apparently, there are similar reactions by 2,3 …
